MUSIC-PLAYING DEVICE.

Application filed May 25, 1911.

To all whom it may concern:

Be it known that I, CABLE C. CONWAY, a citizen of the United States, residing at NewYork, in the county of New York and State of New York, have invented a new and useful Music-Playing Device, of which the following is a specification.

This invention relates to a pneumatic musical instrument and the music sheet therefor. Perforated music sheets have commonly been provided with marks adja cent to the perforated notes indicating the melody.

This invention relates to the marking of the music sheets in a different way so that the operator can readily distinguish the marks of the different sections of the instrument as for example, the bass and treble, and readily control the operating devices so as to accent the proper notes in said sections.

Reference is to be had to the accompanying drawing in which Figure 1 is a diagrammatic view of a. portion of a pneumatic piano action and controlling devices and showing the music sheet, and Fig. 2 is aview of a portion of the music sheet on enlarged scale.

The invention is shown as applied to an ordinary type of musical instrument having bellows 10 and an action divided into a plurality of sections as bass and treble sections 11 and 12. These as usual are connected with the bellows by two chokers 13 and 14. These two chokers are controlled by pneumatics 15 and 16 to which air is admitted by the operation of a pair of movable operating elements, as buttons 17 and 18. The music sheet 20 is provided with the usual note perforations 21 and with two sets of marks 22 and 23, the marks 22 indicating the notes of the bass section that are to be accented, while the marks 23 indicate the notes of the treble section that are to be accented.

In order to provide for readily distinguishing the accented notes of each section of the action and for reducing error due to touching the wrong accenting button, the marks 22 in the bass section are colored red while the marks 23 in the treble section are Specification of Letters Patent.

colored blue and the button 17 controlling the bass action is colored red while the button 18 controlling the treble action is col-- ored blue. It will be seen, therefore, that the two buttons have surfaces readily distinguishable from each other and that the marks indicating the notes to be accented of each section are of the same appearance as the button for controlling that section so that the operator when he sees a red mark about to pass over the tracker will know that he must press the red button, for example. In this way all confusion between the diflzerent sections of the action is avoided and the operator is enabled to provide the proper accent without stopping to consider whether the note about to be accented is in the treble or bass section. It will be understood, of course, that the invention is equally applicable to instruments divided in any other Way.

While I have illustrated and described a preferred embodiment of the invention, I am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described but hat I do claim is 1. The combination with a pneumatic musical instrument having an action divided into a plurality of sections, and a movable element for controlling the operation of each of said sections to accent the notes thereof, said movable elements having readily distinguishable surfaces, of a music sheet having provisions for controlling the sounding of the notes and provided with marks for indicating the notes to be accented, the marks for those notes in each section being of the same appearance as the movable element for controlling the accent of that section.

2. The combination with a perforated music sheet having each note perforation to be accented provided with a designative mark just in advance of, and in line with, it, those in the treble and bass sections being of different distinctive colors, of a buttonof each of said colors, each for control- In testimony whereof I have hereunto set ling the accent of the notes in one of said my hand, in the presence of twosubsoribing sections, and means whereby when a marked Witnesses.
